TRAVERSE MECHANISM FOR WINDING-MACHINES.

Specification of Letters Patent.

Patented Sept. 11, 1911?.

Application filed October 30, 1911, Serial No. 657,529. Renewed February 10, 1916. Serial No. 77,525.

To all whom it may concern:

Be it known that I, HOWARD D. CoLMAN, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Traverse Mechanisms for Winding-Machines, of which the following is a specification.

This invention relates to spoolers and winders, and its object is to provide means -for traversing the thread back and forth upon the spool or cheese, the traversing means being of such character that it may be operated very rapidly and thus permit of a great increase in the speed of Winding.

In the accompanying drawings, Figures 1 and 2 are top plan views of opposite endr portions of a winder embodying the features of my invention. Figs. 3 and 4 are vertical sectional viewsof the portions shown in Figs. 1 and 2 respectively. Fig. 5 is a sectional view of the yarn-traversing means. Figs. 6, 7 and 8 are views in a series illustrating the operation of the yarn-traversing-means. Fig. 9 is a vertical sectional View showing a thread as being wound upon the thread container. Fig. 10 is a detail view of a part comprised in the traverse motion. Fig. 11 is a fragmental side elevation illustrating the action of the traversing means. Fig. 12 is a top plan view of a portion of the traversing means. Fig. 13 is a fragmental side elevation illustrating the means for actuating the yarn-traversing means. Fig. 14 is a continuation of Fig. 13. Fig. 15 is a section on' line 15-15 of-Fig. 14. Fig. 16 is-a section on line 16-16 of Fig. 13. Fig. 17 is a section taken in F 1g. 14:. I

The embodiment herein shown of my invention is a machine for winding yarn from bobbins a onto cores 0 (Fig. 11) to form cheeses d. Said machine comprises an elongated framework 1 having two parallel sides, each side being furnished with means for rotatablysupporting bobbins and.

the plane of line 17 -17 of.

In the present embodiment the cores or cheeses are rotated through peripheral contact with rolls 2, one being provided for each side of the machine. The rolls 2 may be driven in any suitable manner, as, for instance, by means of belts (not shown) extending over pulleys 3 (Fig. 2) fixed upon the journals of the rolls.

At each side of the supporting frame is a series of brackets 4, each mounted so as to be capable of a slight pivotal movement, for a purpose to appear hereinafter. In this instance each bracket 4 is provided with a bearing sleeve 5 (Fig. 9) which is rotatably mounted on a rod 6 the ends of which are supported in brackets 7 fixed to the machine framework. As shown in Fig, 9 the point of pivotal support for each" bracket 4 is at one side of its center of gravity, so that the bracket tends to occupy the position represented in said figure.

Each bracket 4 has bearings 8 at its upper end. 9 is a cheese-supporting lever provided upon one side and between its ends with a "pivot 10 which is mounted in the bearings 8 ter.

The yarn is traversed back and forth to buildup the cheese by means to be now described. Fixed in the supporting framework in front of each roll 2 is a rail or flange 22 and at the rear ordnner side of said rail is another rail 23, said rails being secured together by screws 24. Between SaId I'HJlS are clamped pairs of plates 25. Each plate has an edge 26 (Figs. 5 and 10) extendmg above the horizontal plane of the upper edge of the rails, an edge 27 in a still higher plane, and an inclined or cam portion 28 extending between said edges. The cam portions 28 upon each pair of plates are at the limits of the to-and-fro motion of the yarn. The yarn is moved laterally in one direction by an endless traveling tape 29 having yarnengaging projections 30 thereon, and the.

yarn is moved in the opposite direction by a similar endless tape 31 having like projections 32. Said tapes travel through guideways formed between the rails 22 and 23 and the plates 25. The tapes may be driven by any suitable means. Herein I have shown two pulleys or band wheels 33 and 34 (Fig.

1) arranged for rotation in opposite d1rec-- pulleys may be driven in any suitable manner, as, for example, by means of worms 35 fixed upon a shaft 36 connected to one of the rolls 2, said worms engaging worm-wheels 37 fixed to the pulleys 33 and 34. Each of said pulleys is provided .at its lower side with a peripheral flange 38. 1 (Figs. 16 and 17) to prevent the tapes from running off the pulleys. Each pulley also has a peripheral seriesof pins 39 adapted to enter" openings 40 in the tapes. Herein I have shown the projections 39 as being longer than the thickness of the tape, .althou h it will be evident that said pins may be 0 less length. In order to prevent interference of the projections upon the wheel 34 with the tape 29 when said projections are of the length therein shown, the tape 31 maybe made wider than the tape 29 and the projections 39 upon the wheel 34 may be located in a plane below the plane of the lower edge of the tape 29, as indicated in Figs. 14 and 17.

At the opposite end of the machine the tapes extend around idlers 41 and 42 which may be mounted for adjustment as represented in Figs. 2 and 4 in order that the tapes may be kept under proper tension.

' In order to hold the tape 29 out of contact with the tape 31 at the ends of the machine I provide guides-43 (Figs. 1, 2 and I 15), past which guides the tape 29 extends.

The operation of the traversing means will be best understood by reference to Figs. 5 to 8, 11 and 12. Figs. 11 and 12 represent a projection on the tape 29 as having carried the thread to the left across the periph cry of the cheese, the projection being shown as forcing the thread up the inclined or cam surface 28. As soon as the yarn has been carried above the projection, the yarn will of course be free from said projection, and

the tension of winding will cause the yarn to spring into or toward a straight line j oining the bobbin and the cheese. Atthis moment 2. projection upon the tape 31 traveling the opposite direction catches the yarn and moves it toward the right across the periphery of the cheese. After the right- .or packages,

is released from the tape 31 by. the righthand cam surface 28, and is then picked'up' by a projection upon the tape 29 and again moved to the left. The tapes thus alternately pick up the yarn and move it over the periphery of the cheese.

It will be seen that the traversing means is rotatory, no reciprocating parts being used, and that consequently the speed of operation is not limited by the momentum of reciprocating devices, as in prior machines. A great increase in windingspeed by rendered possible. 3

The surfaces 26 of the plates 25 are preferably in a plane above the upper edge of the tape 29 so as to support the yarn out of contact with such upper edge. Guide plates 44 fixed to the rear side ofthe rail 23 pre-' is there vent the yarn running to a small cheesefrom bearing against the upper edge of thetape 31. (See Figs. 5 and 9.)

Referring to Fig. 9: It is desirable to keep 2 the yarn-traversing means andthe periphcry of the cheese close together during the winding operation. *F or this purpose the bracket 4 is pivotally supported, as hereinbefore described, and a stud 45 onthe' lever 9 is arranged to lie against a cam' or guidesurface 46 on the bracket 7 said guide surface being of such form that as the cheese-in creases in diameter the center ofithe cheese will move upwardly in such'a path as will cause the periphery'of the cheese to remain close to the yarn-traversing means.

The means for detecting exhaustion of the yarn and for throwing the'cheeseout}; of operation will'not be described, as said means forms no part of this invention.
